japan didn't really seem to have any other ideas. so whoever the new coach is needs to give them that mental strength, that belief, and they need to give them at least a plan b if not a plan c as well. >> throughout the games, what impressed carroll the most were the many unexpected outcomes of the matches. >> people like to see a surprise or two. i think that was why people liked it. it wasn't just one lucky win here. there were three or four or five countries that really made it difficult for the big teams. and that makes it fun to watch. it's never nice watching any sport, especially football, i think, when it's obvious this team is going to win and this team is weaker. so i think that, for me, was the most enjoyable aspect, that these weaker nations went out on the pitch, took their opportunity, and they really fought, really battled until the end of the game. if the other team was going to beat them, they made sure they had to work hard to win.
